A series of catalysts for methanol synthesis were prepared by vacuum freeze drying. Catalytic properties of catalysts were investigated with XRD,H2-TPR,CO2-TPD,TEM,EDAX, and BET and evaluation of catalytic activity was conducted in a micro fixed-bed reactor. The results showed that the catalysts for methanol synthesis prepared by vacuum freeze drying had high specific surface area,high activity and high selectivity.% 采用真空冷冻干燥法制备了一系列CuO-ZnO-ZrO2甲醇合成催化剂，在微型固定床反应器上考察了其对CO2加氢合成甲醇的催化性能及影响，并用XRD、H2-TPR、CO2-TPD、TEM、EDAX、BET等手段进行了表征。研究结果表明，采用真空冷冻干燥法能够制备出高比表面积、高活性、高选择性的甲醇合成催化剂CuO-ZnO-ZrO2。
